Apple Activity app on the iWatch and the companion app on the iPhone offer the most rudimentary reporting of activity stats. Want to get your most miles walked/run/biked in the past 30 days? No go! Want to get you total steps in November? No go! Want to get your weekly average calories plotted vs. time? Keep on dreaming! Does anyone know of an app that accesses the Activity app data and can present the type of statistics I mentioned above? I think that if Apple doesn't want to dedicate resources to improve their own apps, they should at least provide an API to developers. Sure there is a market for this stuff. I for one would be willing to dish out 10, 20, heck even 30 bucks to be able to track my activity over time, not just since midnight.
